Dear Dr. silvia:
I have a small question about units of the curvature. If I define my basic length unit as mm, what will be the units of curvature given by the recorder section deformation output. Is it (rad/mm) or (1/mm).
Thanks in advance

should be 1/mm
but test it out.

by the way, rotation, for example, is inch/inch -- small deformation theory applies here, where theta=tan(theta)

actually, it probabily is rotation/length = radians/length.....
again, it should give you the same results for small defo.

There's not difference, since 1 rad is a pure number which doesn't need a unit symbol. So, for large or small deformations, you can use both.
